Personal loan disaster

I used to love FNB so much that i have considered it my permanent home, this is a bank that i have been with since i was a student with a student account until i became a private client. But lately they have been giving the worst service that makes me embarrassed just to be associated with them. I opened a personal loan because i had an emergency, the money was loaded and i paid or settle the account in 10 days. 1.FNB continued to debit my account for a premium even though the account is settled. 2.I called them and they promised me that the money will be credited within 10 working days, that has not happened and there is no communication. 3.I have asked them to remove it from my FNB Banking profile, that has not happened even though i was promised. 4. Today they have loaded the loan account on my Transunion as owing, and my credit rating went down. The worst part is i am currently in the process of looking for a house and my credit score just reduced by 10 points because of them.

I have called many times, i used their useless chat on the app and i have always been referred to the personal home department which have promised the same thing over and over again. AND NOW I AM JUST TIRED
